This leads to a loss of atrial mechanical function with increased risk of progressive atrial chamber dilatation and cardiac thromboembolism. AF results in an irregular and usually rapid heart rate if untreated. Why worry about AF? AF is the most common sustained cardiac arrhythmia seen in clinical practice. It is associated with increased morbidity, mortality and preventable stroke (AF is associated with a five-fold increased risk of stroke). The incidence and prevalence increase with age; lifetime risk of developing AF is one in four for those aged 40 years and older.1,2,3 Patterns of AF 3,6 AF is a chronically progressive disease and, as such, rhythm control strategies should be undertaken at the earliest possible stage. Table 1: AF as a progressive condition Paroxysmal Intermittent AF reverting spontaneously to sinus rythm within 7 days(usually within 48 hrs) probability of reverting after 48hrs. Persistent AF > 7 days or requires electrical or pharmacological termination. Long –standing Persistent AF longer than one year Permanent AF Permanent presence of AF is accepted by the patient and physician. P waves Clinical Assessment: Manual pulse check. ECG is mandatory to confirm rhythm, assess rate, and identify other pathologies including cardiac ischaemia, left ventricular hypertrophy or pre-excitation. Patient history and physical examination; in particular, assess for haemodynamic compromise, heart failure and cardiac ischaemia. Stroke risk assessment (see Algorithm A). Blood Tests: renal, hepatic, thyroid (exclude hyperthyroidism), clotting factors (baseline), electrolytes, BSL (exclude diabetes), full blood count (exclude anaemia). Consider AF in relation to the patient’s overall cardiovascular risk. 1 Echocardiogram recommended especially in patients with symptomatic AF, known or suspected heart disease or cardiac risk factors to assess cardiac function and detect structural abnormalities.3 Refer to an Emergency Department or Specialist when necessary. Atrial Fibrillation – Management Principles Management Priorities (SO - AF): Rate Stroke prevention – consider antithrombotic therapy to reduce the risk of systemic thromboembolism that can lead to stroke and death See Algorithm A Or Rhythm control – strategy in the long-term See Algorithm B Assess and relieve symptoms – this is usually obtained by rate control in the short-term Factors – treat associated or causative factors; may abort the arrhythmia Note that interim rate control is still necessary for most patients in whom a rhythm control strategy is chosen. Depending on the patient’s response, the strategy initially chosen may be unsuccessful in which case the alternative strategy is adopted. Regardless of whether a rate or rhythm control strategy is used, attention to antithrombotic therapy to prevent thromboembolism is essential. Consider referral: First episode of AF of less than 48 hours duration refer to local ED for possible cardioversion. Symptomatic patient. Underlying or suspected cardiovascular disease. Management difficulties. Requires antiarrhythmic treatment. Antithrombotic treatment is problematic or contraindicated. Refer all patients with atrial flutter as catheter ablation is often the most effective initial treatment. Follow Up: Regular follow-up – review the patient at least annually. Reassess AF pattern – has it changed? Reassess antithrombotic need – have indications for antithrombotic treatment changed? Risk profile assessment – e.g. new diabetes or hypertension. Review current therapy effectiveness – symptoms, heart rate and side-effects of antiarrhythmic medications (look for QT prolongation). Patient education – including cardiovascular risk factors and antithrombotic therapy. Provide patients with a structured care plan for follow up and management of AF. 2 12 lead ECG, biochemistry, other investigations as indicated. Holter monitoring may be indicated if unsure of treatment response to rate or rhythm control. Consider exercise testing to assess effective ventricular rate control in younger, active patients. 3 Algorithm A – Stroke Risk Stratification and Antithrombotic Therapy Patient with AF (Irrespective of AF pattern) Previous thromboembolic event No Yes Non-valvular AF AF in a patient without the presence of mitral valve disease, prosthetic valve or valve repair.

Options include no antithrombotic treatment, aspirin 75 -300mg daily or oral anticoagulant (OAC). Aspirin or OAC is unlikely to have a net clinical benefit unless HAS-BLED score is low. See page 6,7 ≥2 One major risk factor or ≥2 clinically relevant non-major risk factors New OAC is preferred to wafarin4,6. If using warfarin, target INR 2.5 (range 2-3*). Use low molecular weight (LMW) heparin when commencing warfarin until INR is therapeutic. ++ If HAS-BLED ≥3, consider referral to a cardiologist. * Embolic risk if INR < 2.0 and risk of bleeding with high INR. Reassess thromboembolic risk and need for antithrombotic therapy at least annually 4 Table 2: CHA2DS2-VASc, a more precise stroke risk calculator Major Stroke Risk Factors Clinically relevant non-major stroke risk factors Heart failure Previous stroke, transient ischaemic attack (TIA),or systemic embolism Age 75 years Moderate to severe LV systolic dysfunction (LV EF < 40%) Hypertension and /or Diabetes mellitus Female sex and/ or Age 65–74 years Vascular disease Letter Risk Factor Score C Congestive heart failure/ left ventricular dysfunction 1 H Hypertension 1 A Age 75 2 D Diabetes mellitus 1 S Previous Stroke/ TIA/ thromboembolism. 2 V Vascular disease (eg. prior myocardial infarction, peripheral artery disease, or aortic plaque) 1 A Age 65–74 1 Sc Sex category (i.e. female sex) 1 Note: maximum score is 9 since age may contribute 0, 1, or 2 points 9 Adapted from Camm, Kirchoff et al, 20103 Annual Stroke Risk Based on CHA2DS2-VASC scoring system4 The expected stroke risk rate is: 0.0%/yr in those people with a CHA2DS2-VASC of 0 1.3%/yr with score of 1 2.2%/yr or higher with score of 2 or more CHA2DS2-VASc score=1: Due to the lack of clinical trial evidence for preferred antithrombotic treatment in patients with a CHA2DS2-VASc score of 1, the 2014 ACC/AHA/HRS guidelines6 recommend that no antithrombotic therapy or treatment with an OAC or aspirin may be considered in these patients. Further, female patients who are aged <65 years with lone AF will have a CHA2DS2-VASc score of 1 by virtue of their gender. They are generally at low risk and the option of no antithrombotic therapy should be considered4. Treatment recommendations should always be based on an informed discussion with the patient taking into account the likely net clinical benefit of antithrombotic treatment. 5 Table 3: HAS-BLED Bleeding Risk Score The HAS-BLED (hypertension, abnormal renal/liver function, previous stroke/transient ischaemic attack (TSI), bleeding history or predisposition, labile INR, elderly >65 years, drugs/alcohol concomitantly) tool was developed to provide a risk score to estimate the 1-year risk for major bleeding 7. Letter Clinical Characteristic Points Awarded H Hypertension (defined as SBP > 160 mmHg) 1 A Abnormal renal and liver function (1 point each)* 1 or 2 S Previous Stroke 1 B Bleeding history or predisposition 1 L Labile INR results 1 E Elderly (>65 years) 1 D Drugs or alcohol (1 point each) 1 or 2 Max 9 points *’Abnormal kidney function’ is defined as the presence of chronic dialysis or renal transplantation or serum creatinine ≥ 200µmol/L. ‘Abnormal liver function’ is defined as chronic hepatic disease (e.g. cirrhosis) or biochemical evidence of significant hepatic derangement (e.g. bilirubin >2 times ULN, in association with AST/ALT/Alkaline phosphatase > 3 times ULM. The European Society of Cardiology (ESC) 2010 Atrial Fibrillation guidelines suggest a HAS-BLED score of ≥ 3 indicates a high bleeding risk. Caution and regular monitoring would be required in any use of antithrombotic therapy in such an AF patient 3,7. Score 0-1 Bleeding risk calculation (% bleeds per 100 patient-years) Low risk (1.1%) 2 Intermediate risk (1.9%) >3 High risk (4.9%) If CHA2DS2-VASc score ≥ 2 with a HAS-BLED score≥3, consider referral to cardiologist. If CHA2DS2-VASc score is 1 with a HAS-BLED score≥2, antithrombotic therapy may not be warranted as bleeding risk may exceed thromboembolic risk. Risk-benefit should be discussed. If uncertain discuss with a cardiologist. 6 Algorithm B – Atrial Fibrillation Management Cascade Patient presents with symptoms suggestive of AF or irregular pulse detected by practitioner Record 12-lead ECG Consider Holter monitor if suspected Paroxysmal AF If haemodynamically unstable: Treatment of underlying disease/precipitant cause to prevent deterioration of AF: eg hypertension, heart failure, IHD, obesity, obstructive sleep apnoea Rate-control strategy4 Aim: control the ventricular rate Preferred initial option for: Initial diagnosis of AF Control rate and refer to Emergency Department or Specialist. May need emergency cardioversion Clinical assessment Rhythm-control strategy4 Consider antithrombotic treatment See Algorithm A Aim: revert AF to sinus rhythm Preferred initial option for: Minimal or no symptoms People with unacceptable arrhythmia related symptoms People with coronary artery disease People presenting for the first time with nonvalvular AF People with contraindications to antiarrhythmic drugs People unsuitable for cardioversion People without congestive heart failure Older people (>65) Assess indications for rate and/or rhythm control AF secondary to a treated/correctable precipitant People who are intolerant of rate-controlling drugs People with congestive heart failure Younger people (<65) Assess response Symptomatic control achieved Remains symptomatic Consider Specialist referral Arrange follow up Note: Rate control: Use -blockers or rate-slowing calcium channel blockers. Note that digoxin is effective at controlling heart rate at rest but not during exercise, use only in sedentary patients, digoxin has a secondary role in patients with congestive heart failure. 1 Rhythm control: Use amiodarone, sotalol or flecainide only after expert advice. 7 Algorithm C – DC Cardioversion Guidelines Consider cardioversion in highly symptomatic patients when other therapy has failed Cardioversion is contraindicated in digitalis-toxic patients Patient with AF Stable Unstable Unstable patient with rapid ventricular rate that has not promptly responded to 3 h l i l Non-urgent cardioversion AF of > 48hrs or of uncertain duration: Therapeutic anticoagulation for 3/52 pre-cardioversion and at least 4/52 post cardioversion then consider long-term antithrombotic therapy based on stroke risk (Algorithm A) and/or risk of AF recurrence/ presence of 3 thrombus. Urgent cardioversion AF of < 48hrs: AF> 48hrs or IV low molecular weight heparin (therapeutic dose) pre-cardioversion and: CHA2DS2-VASc score 0: no post cardioversion anticoagulation CHA2DS2-VASc score 1: OAC for at least 4/52 post –cardioversion then consider long-term antithrombotic therapy based on stroke risk (Algorithm A) and/or risk of AF 3 recurrence/ presence of thrombus. of uncertain duration: Refer to specialist centre for TOE + cardioversion After cardioversion, consider referral to a cardiologist / electrophysiologist Synch button ON for each shock when cardioverting* Patient sedated and monitored with Anaesthetist, ED Physician or GP Anaesthetist present and managing airway*. Defibrillator Energy Monophasic: 200J Biphasic: 100-150J Note: A delay once shock button is depressed is normal while the defibrillator searches for R or S wave to synchronise with. *Equipment required: *Anaesthetic agents required, : IV access Monitoring equipment Airway management equipment Emergency drugs on hand Short acting sedation (propofol or midazolam) Opioid (e.g. fentanyl) Reversal agents (e.g. flumazenil/ naloxone) available Pharmacological cardioversion can be considered if AF is of short duration since onset. In the absence of structural heart disease flecainide is recommended. Amiodarone does not achieve cardioversion in the short-medium term.3,4Use amiodarone or flecainide only after expert advice. 8 Atrial Fibrillation – Frequently Asked Questions (FAQs) What happens if warfarin needs to be stopped for general surgery? Pre-Operative Patients with AF who have a high short-term thromboembolic risk (e.g. mitral stenosis, prosthetic valves, previous thromboembolic event) should have warfarin withheld five days before anticipated date of surgery, and IV heparin cover or LMW heparin (at arterial doses) commenced when INR has fallen to below 2. For other patients, warfarin can be ceased for five days pre-operatively without heparin cover. Post-Operative Recommence usual antithrombotic therapy without loading dose immediately post-op, or day one post-op, assuming adequate haemostasis. How do I safely use dabigatran, rivaroxiban or apixaban in my nonvalvular AF patient? The WA New Oral Anticoagulant Prescribing Guidelines (including recommendations for managing NOACs for procedures) can be found at: http://www.watag.org.au/watag/docs/WANewOralAnticoagulantPrescribingGuidelines.pdf What to do if the patient with AF is on antiplatelet therapy? It is not uncommon for a patient with atrial fibrillation to also need antiplatelet treatment for coronary heart disease; unfortunately there is a lack of sufficient evidence to provide clear management pathways for such patients. The combination of single antiplatelet therapy with anticoagulation significantly increases bleeding risk (up to two-fold or higher), however the greatest risk is in patients on triple therapy, i.e., dual antiplatelet therapy and a Vitamin K antagonist or NOAC. However, dual antiplatelet treatment provides the highest post-stent protection and a NOAC or warfarin alone is not effective at preventing stent thrombosis. Each patient must be assessed individually and treatment should be based on artherothrombotic, cardioembolic and bleeding risk. Early discussion with a cardiologist is highly recommended and, where possible, aim for the shortest necessary duration of triple therapy. When should I consider specialist referral for catheter ablation? Consider referral to an electrophysiologist for discussion of the role of ablation in patients who have symptomatic AF despite medical therapy, including use of one antiarrhythmic medication, or those who are intolerant of, or those who do not wish to take antiarrhythmic drugs. As results of ablation are better in paroxysmal atrial fibrillation, referral should be considered earlier in suitable patients. Left atrial catheter ablation is a complex ablation procedure with possibly severe complications and expert advice is required before recommending catheter ablation in an individual patient with symptomatic AF.
